He did.
Texas is such a large state that people don't always know what is going on in other parts of the state. To my knowledge we have never privatized taxes for greedy furriners. IIRC, several years ago someone built a toll road in west Texas which was a total flop. I don't think any taxes were involved but I'll have to check it out.
Houston collects $50 million in profits a year on their toll roads. You bet, Cintra wanted to buy this cash cow. Cintra continues to keep parts of their contracts secret. So much for "transparency". LOL
Failure to find evidence of "privatizing taxes for greedy furriners," whatever that means, is not evidence of Texas being "nearly 100% free of large public/private partnerships."
